Grundfos end-suction pumps are used in water supply, industrial pressure boosting, industrial liquid transfer, HVAC (heating, ventilation and air-conditioning), and irrigation. Grundfos end-suction pumps are multi-purpose pumps suitable for a variety of different applications requiring reliable and cost-efficient supply. End-suction pumps are used in five main areas of application: water supply, industrial pressure boosting, industrial liquid transfer, HVAC and irrigation. The Grundfos NB/NBG pumps are all non-self-priming, single-stage, centrifugal volute pumps with axial suction port, radial discharge port and horizontal shaft. The NB/NBG range consists of close-coupled pumps with their main dimensions in accordance with either EN733 or ISO2858.

Grundfos TP and TPE vertical in-line volute pumps are used in a variety of applications. The pumps are all single-stage, in-line centrifugal volute pumps with standard motors and mechanical shaft seals. The pumps are of the close-coupled type, i.e. pump and motor are separate units. Consequently, the pumps are less sensitive to impurities in the pumped liquid than similar pumps of the canned rotor type. Two different models of vertical in-line volute pumps are available. Please note that there are a number of specific product variants available for each model. Detailed information on these variants can be found in Grundfos WebCAPS.

The horizontal multistage pump CM (=Centrifugal Modular) has been created with compactness and modularity as two of its central features, making numerous configurations possible. The pump is basically composed of a series of interchangeable modules, all of which have been designed to work together seamlessly, no matter what the application. The pumps are of the close-coupled type. The difference between the CM and the CME pump ranges is the motor. CM pumps are fitted with mains-operated motors, whereas the motors for CME pumps have an integrated frequency converter.

The pump features soft starting and protection against dry-running, upthrust, overvoltage, undervoltage, overload and overtemperature. The motor is a single-phase motor of the permanent magnet rotor type ensuring optimum efficiency within a wide load range. The motor is fitted with a replaceable end cover with socket.
